bananza

I have two Gros Michels potted that I took inside in October/November when temperatures were at 4 celsius. I had the same problem described here with my larger GM after taking both plants inside. The plants were not showing distress out in the cold, but once inside the larger one immediately began wilting, and soon the whole plant just turned brown. I believe it was the temperature change and light change (under a lamp).

So I drained it and cut it down. I recently put honey and calcium powder over the knob. Hoping planter soil will dry out. No issues with the other one.

It kind of looked like it had the Panama Wilt disease.
